Multi-token provisioning, online purchase transaction processing, and card life cycle management systems and methods

ABSTRACT

An example method for provisioning tokens in a networked computing environment including merchants participating in payment networks involves (1) receiving a request to provide a merchant with a secondary token for a purchase card having an associated primary account number (PAN), wherein the secondary token (i) is associated with a secondary payment network and is to serve as an alternative to a primary token for the purchase card that is associated with a primary payment network, and (ii) comprises a computer-generated identifier of the purchase card that is available for use in place of the PAN when processing network-based financial transactions involving the purchase card, (2) generating the secondary token for the purchase card, and (3) transmitting the secondary token for the purchase card, wherein the secondary token for the purchase card is thereafter utilized by the merchant to process one or more network-based financial transactions involving the purchase card.

CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims priority to, and is a continuation of, U.S. application Ser. No. 18/092,426, filed on Jan. 2, 2023, and entitled “Multi-Token Provisioning, Online Purchase Transaction Processing, and Card Life Cycle Management Systems and Methods,” which is a continuation of U.S. application Ser. No. 16/396,323, filed on Apr. 26, 2019, and entitled “Multi-Token Provisioning, Online Purchase Transaction Processing, and Card Life Cycle Management Systems and Methods,” the contents of each of which are incorporated by reference herein in their entirety.

BACKGROUND

Merchants processing purchase card transactions, including in online shopping contexts, are charged processing and/or service fees to realize payment for such transactions. Naturally, merchants have a business interest and desire to not only minimize such transactions costs, but also to establish processes that make those costs more predictable. Commentators have called for more transparency and standardization regarding interchange and the cost associated with processing bankcards. The Durbin Amendment to the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 was intended to address this issue for businesses and inure to the benefit of both merchants and consumers. Among the pro-competitive policies the Durbin Amendment facilitated are capped interchange fees charged to merchants every time they processed debit card transactions.

In e-commerce contexts, for example, merchants may obtain and store network-based tokens to facilitate payments in place of storing actual card numbers. In at least some known market contexts, merchants have to pay a different fee based on the bank that issued the debit card. The primary token obtained from token service platform(s) of global front-of-card brands (e.g., Visa®) may contain processing restrictions that may prevent merchants from using a primary token to route a payment transaction to an alternate network (e.g., Pulse®) that may be enabled on the actual card. The commercial framework for secondary tokens is based on transactional and other service fees. In at least some known business contexts, merchants are unable to effectively and efficiently establish purchase or payment transaction routing preferences on a per transaction basis, so as to predict, plan for, and minimize transaction costs, and maximize net profits. It would thus be beneficial to both merchants and consumers at large to provide a means for preserving merchant routing choice when no other alternative exists in the market today.

SUMMARY

The disclosed systems, methods, and associated software enable merchants to maximize their savings and establish processes to optimize payment processing to benefit both their operations and their customers' experiences. Merchants are thereby enabled to have co-resident tokens tied to a single customer payment account and use those secondary tokens to have the choice that they should have under the Durbin Amendment, but currently do not. Merchants are enabled to obtain a token that is not restricted to route to the global payment network and to route a tokenized stored credential transaction to any network enabled to support an alternative (e.g., secondary) token. In addition, the disclosed systems, methods, and software provide a framework for standardization and/or regulatory compliance of payment processing in market contexts involving both front-of-card brands and back-of-card brands attached to the same purchase card being used in respective transactions.

With the systems, methods, and software disclosed herein, merchants can, after obtaining a primary token from systems associated with the front-of-card brand, obtain a secondary token from a secondary token service provider than can be used to route transactions to the alternate network (e.g., Pulse®) with the expectation that authorization requests can be processed successfully. As such, the disclosed systems, methods, and software provide merchants routing choice for tokenized card-on-file (COF) transactions by enabling secondary tokens to be stored and otherwise maintained/managed side-by-side with primary, front-of-card, tokens. Furthermore, life cycle management (LCM) processes provided by the disclosed systems, methods, and software enable the side-by-side tokens to be always synchronized in merchant systems.

The below-described systems, methods, and software enable networks to compete for merchant transactions and gives merchants greater control of routing decisions. Experiences of merchant customers (e.g., registration of profile on e-commerce websites and/or online checkout processes) are not, or are only negligibly, affected. Meanwhile, merchants may pass cost savings of practicing the disclosed systems, methods, and software to the customers.

With the side-by-side tokens provided by the disclosed systems, methods, and software, merchants have: a primary token, assigned by the front-of-card brand that may be subject to routing restrictions; and an alternate (secondary) token that provides routing support to participating alternate (e.g., debit) payment networks. The general process flow of the disclosed systems, methods, and software includes: a) cardholder adds primary account number (PAN) to profile; b) merchant identifies tokenized COF-enabled networks via bank identification number (BIN) file inquiry; c) merchant requests and obtains a token from a supported token service provider; d) merchant adds tokenized payment credentials to cardholder profile; and e) merchants have the security of tokens and the power of choice.

To practice the disclosed systems, methods, and software, merchant requirements are such that established systems may be utilized and additional investment in hardware and infrastructure is not necessary, or is, at most, negligible. The disclosed systems, methods, and software are integrated into existing systems and networks and are readily adaptable to present and future hard and network infrastructures. In practice, merchants' operations impacted minimally as compared to present business practices. For example, the disclosed systems, methods, and software require merchants to: (i) request and store multiple tokens for each actual debit PAN; (ii) enable token selection based on preferred network route; (iii) directly or indirectly (e.g., via a service provider) access network BIN files to determine secondary network token support and provider.

In practicing the disclosed systems, methods, and software, merchants may integrate, for example, with Discover®'s token service platform (e.g., DDX®). In such cases, the set up for merchants includes: (A) identifying eligible BINS during card enrollment (e.g., via BIN files); (B) establishing token request and lifecycle management processes; (C) determining network routing preferences; and (D) enabling payment system to route according to preferences.

In operation of some embodiments of the disclosed systems, methods, and software, merchant customers/cardholders provide their personal and account data to merchant e-commerce website interfaces as usual. Customers see their masked actual PAN, and have no awareness of tokens. The merchants' databases see a customer's actual PAN name, a unique token PAN, network routes (e.g., Visa®), and token type (e.g., primary for Visa®). Additionally, with the disclosed systems, methods, and software, the merchant database sees another (e.g., a second) unique token PAN for the respective actual PAN name, and for another (e.g., a second) network route (e.g., Pulse®), with an associated (e.g., alternate) token type for the second unique token PAN.

DETAILED DESCRIPTION

FIG. 1 is a schematic diagram of a networked computing environment (100) for provisioning tokens, processing purchase or payment transactions, and/or automatically updating tokenized purchase card account data (142) of customers (104) of online merchants (108) participating in payment (e.g., debit) networks, according to an embodiment of the disclosure. Networked computing environment (100) includes a plurality of network entities, including a cardholder (104). Cardholder (104) has possession and/or control (e.g., custodial control) over a purchase card (106) (e.g., a debit, credit, gift, or stored value card) and its associated purchase card (106) account data (110). In an example, cardholder (104) uses a computing device (102) to communicate and otherwise interact with a website of an online merchant (108), including to perform online shopping and make online purchases of goods and/or services offered by, or to otherwise make payments to, merchant (108). The physical card (106) includes card account data (110) including a card number, an expiration date, and a card verification value (CVV) number. Online shopping by cardholder (104) using purchase card (106) enables the cardholder/customer (104) to initiate and complete online purchase transactions at online merchant(s) (108) without having to present the physical card (106). Cardholder (104) may similarly initiate any other payments to merchant (108) besides for online shopping and/or non-e-commerce contexts, including, without limitation, cardholder (104) pre-authorized payments initiated by merchant (108) on behalf of cardholder (104) (e.g., installment and/or recurring payments). Purchase card (106) includes a Bank Identification Number (BIN) (172). In an example, the BIN represents the first 6 to 8 digits of the card number. In another example, the BIN is at least 1 digit long, but less than 6 digits long. In yet another example, the BIN is longer than 8 digits long, but less than the total number of digits of the card number. In an example, the purchase card (106) is a multi-BIN enabled purchase card (106).

The networked entities in networked computing environment (100) include one or more merchants (108). In an example, merchants (108) are e-commerce merchants that maintain websites on the World Wide Web (WWW) for offering goods and/or services for sale to cardholders (104). In another example, merchants (108) are engaged in both e-commerce and non-ecommerce transactions (e.g., a retail store having an e-commerce website in addition to “brick and mortar” store(s)). In yet another example, merchants (108) receive installment and/or recurring payments (e.g., health club memberships where the merchant stores purchase card information one file, but is not necessarily an online e-commerce merchant). To these ends, merchant (108) utilizes one or more computing and communication devices. These merchant (108) systems include one or more merchant processors (158) in communication with at least one merchant memory device (collectively referred to herein as “merchant memory (166)”). In an example, merchant (108) includes one or more servers (162) which implement and/or otherwise perform, at least in part, the functionality of merchant processor (158) and/or merchant memory (166).

Among other purposes directed to commerce operations, merchant memory (166) stores, as data, a customer profile (174) of the cardholder/customer (104). Cardholder (104) enters their personally-identifying information (PII) for storage in the customer profile (174) and further to the merchant's (108) commercial purpose. Merchant (108) may instead receive the information for the customer profile (174) of the cardholder/customer (104) and then store it in merchant memory (166). The PII includes the cardholder's (104) name, telephone number, and mailing address. The PII includes the cardholder's (104) purchase card (106) information, which the merchant processor (158) may encrypt prior to or during the process of storing the purchase card (106) information in the customer profile (174). Merchant (108) stores, as data, the card BIN (172) of the purchase card (106) in merchant memory (166), including, without limitation, in the customer profile (174). Merchant memory (166) stores, as data, primary (176) and secondary (178) tokens associated with the purchase card (106). In an example, merchant (108) stores, as data, the primary (176) and secondary (178) tokens simultaneously in merchant memory (166) as side-by-side tokens (164). In an example, primary (176) and/or secondary (178) tokens are created and stored during or after encryption and/or tokenization of the cardholder's (104) purchase card (106) information. In an example, the purchase card (106) is a multi-token enabled purchase card (106).

Merchant memory (166) stores, as data, transaction data (182) for purchases and/or payments (e.g., installment and/or recurring payments) of cardholder/customer (104). For instance, cardholder (104) selects goods and/or services from the offerings of merchant (108) on their e-commerce website. The selections are stored in a virtual shopping cart (180), which stores, as data, the identities of selected goods and/or services along with their quantity and unit prices and any applicable sales tax. To complete a transaction and make the purchase, cardholder (104) checks out and merchant (108) provides (e.g., mails and/or makes available for download) the goods/services after merchant (108) successfully receives payment from cardholder (104) for the online purchase.

Merchant memory (166) stores, as data, merchant (108)-defined predetermined network routing preferences (170) for purchase and/or payment transactions by cardholders (104). In an example, e-commerce transactions are routed according to the per transaction cost of processing payments. For instance, the predetermined network routing preferences (170) may specify that routing e-commerce transactions to a secondary token service provider (TSP) (116) is less expensive for merchant (108) as compared to routing e-commerce transactions to a primary TSP (112). In an example, the primary TSP (112) is associated with a payment network (118) for a front-of-card brand (e.g., Visa®) of the purchase card (106). In an example, the secondary TSP (116) is associated with a payment (e.g., debit) network (119) for a back-of-card brand (e.g., Pulse®) of the purchase card (106). Based on the predetermined network routing preferences (170), merchant processor (108) creates and stores, as data, a network route list (173) in merchant memory (166). In an example, merchant processor (108) creates and stores, as data, in merchant memory (166) network route list (173) on a per transaction basis.

The network entities of networked computing environment (100) include a card issuer (120). Issuer (120) has custodial control over account data (142) of purchase card (106) and cardholder data (138) associated with cardholder (104). In an example, issuer (120) is a bank and cardholder (104) is a banking customer of issuer (120). Issuer (120) utilizes one or more computing and communication devices. These issuer (120) systems include one or more issuer processors (126) in communication with at least one issuer memory (139). In an example, issuer (120) includes one or more servers (130) which implement and/or otherwise perform, at least in part, the functionality of issuer processor (126) and/or issuer memory (139).

Among other purposes directed to issuer (120) operations, issuer memory (139) stores, as data, the cardholder (138) and card account (142) data of the cardholder (104). Issuer (120) stores, as data, a transaction ledger (146) for the cardholder's (104) account, including, without limitation, a running list of transactions performed by cardholder (104) using purchase card (104). Issuer memory (139) stores data for life cycle management (LCM) processes (150) and change of state files (154). In an example, LCM processes (150) are used by issuer processor (126) to facilitate updating and/or otherwise changing the cardholder (138) and/or the card account (142) data stored in issuer memory (139). In an example, the change of state files (154) contain data related to a status of the purchase card (106) and or its associated account at issuer (120). In an example, for a particular issued purchase card (106), the change of state files (154) contain data representing a status of purchase card (106) and/or the associated account of cardholder (104) at issuer (120). For instance, change of state files (154) indicate the status of purchase card (106) as active, suspended, and/or closed.

The network entities of networked computing environment (100) include a payment service provider (122), an acquirer (192), and the primary TSP (112). Primary TSP (112) utilizes one or more computing and communication devices. These primary TSP (112) systems include one or more primary TSP processors (184) in communication with at least one primary TSP memory (188). In an example, primary TSP (112) includes one or more servers (186) which implement and/or otherwise perform, at least in part, the functionality of primary TSP processor (184) and/or primary TSP memory (188).

Among other purposes directed to primary TSP (112) operations, primary TSP memory (188) stores, as data, primary tokens (176) for purchase cards (110) of a plurality of cardholders (104). In an example, primary tokens (176) stored in primary TSP memory (188) include primary tokens (176) stored in merchant memory (166). In addition to storing primary tokens (176), primary TSP memory (188) may store purchase card (110) information of cardholders (104). Primary TSP memory (188) stores data for primary TSP (112) LCM processes (190). In an example, LCM processes (190) are used by primary TSP processor (126) to facilitate updating and/or otherwise changing the primary tokens (176) for associated purchase cards (110) in response to changes and/or updates in change of state files (154) stored in issuer memory (134) and/or in association with customer profiles (174) stored in merchant memory (166).

The network entities of networked computing environment (100) include the secondary TSP (116). Secondary TSP (116) utilizes one or more computing and communication devices. These secondary TSP (116) systems include one or more secondary TSP processors (194) in communication with at least one secondary TSP memory (140). In an example, secondary TSP (116) includes one or more servers (136) which implement and/or otherwise perform, at least in part, the functionality of secondary TSP processor (194) and/or secondary TSP memory (140).

Among other purposes directed to secondary TSP (116) operations, secondary TSP memory (140) stores, as data, secondary tokens (178) for purchase cards (110) of a plurality of cardholders (104). In an example, secondary TSP (116) stores the secondary tokens (178) in secondary TSP memory (140) as a token vault (128). In an example, secondary tokens (178) stored in secondary TSP memory (140) include at least one of those secondary tokens (176) stored in merchant memory (166). In addition to storing secondary tokens (178), secondary TSP memory (140) may store purchase card (110) information of cardholders (104). Secondary TSP memory (140) stores data for secondary TSP (116) LCM processes (148). In an example, LCM processes (148) are used by secondary TSP processor (194) to facilitate updating and/or otherwise changing the secondary tokens (176) for associated purchase cards (110) in response to changes and/or updates in change of state files (154) stored in issuer memory (134) and/or in association with customer profiles (174) stored in merchant memory (166).

Secondary TSP memory (140) stores, as data, token request processes (144) and network routing preferences (152). In an example, network routing preferences (152) stored in secondary TSP memory (140) include the predetermined network routing preferences (170) stored in merchant memory (166). In an example, secondary TSP processor (158) updates and/or otherwise changes token request (144) and/or network routing (152) preferences based on corresponding changes made by merchant processor (158) to the predetermined network routing preferences (170) (e.g., based on variations in per transaction routing and/or processing costs).

The network entities of networked computing environment (100) include a Discover® Network (DN) account updater (132). DN account updater (132) facilitates updating secondary tokens (178) stored in merchant memory (166). In an example, utilizing DN account updater (132) in the networked computing environment (100) supplants the need to utilize secondary TSP (116) for updating, deleting, or otherwise changing the merchant (108)-stored secondary tokens (178). DN account updater (132) utilizes one or more computing and communication devices.

FIG. 4 is a sequence and state diagram of a token provisioning process (e.g., process (300)) implemented by the method of FIG. 4 (e.g., method (240)), according to an embodiment of the disclosure. Process (300) begins with a start state (302) and proceeds to block (304), which is performed by cardholder (104). In block (304), cardholder (104) adds his or her card account data (142) to the customer profile (174) of the merchant (108) website. Alternatively, the cardholder (104) may provide the card account data (142) to the merchant (108) through channels other than a merchant (108) website, and merchant (108) store that information in merchant memory (166) and/or elsewhere. From block (304), process (300) proceeds to block (306), which is performed by merchant (108). In block (306), merchant processor (158) reads the card BIN (172).

In branch (317), issuer (120) (e.g., using issuer processor (126)) determines if the cardholder (104) account is verified. If issuer processor (126) determines in branch (317) that the cardholder (104) account is not verified, then process (300) proceeds to end state (310).

If issuer (120) determines in branch (317) that the cardholder (104) account is verified, process (300) proceeds to block (318), which is performed by the selected network (124). In block (318), the selected network (124) receives account verification from issuer (120). From block (318), process (300) proceeds to block (319), which is performed by the selected network (124). In block (319), the selected network (124) transmits the account verification to the primary TSP (112). In block (320), primary TSP processor (184) generates and/or provisions the primary token (176). From block (320), process (300) proceeds to block (322), which is performed by merchant (108). In block (322), merchant processor (158) stores the primary token (176) in merchant memory (166). From block (322), process (300) proceeds to block (324), also performed by merchant (108). In block (324), merchant processor (158) sends a token request (e.g., a request for the secondary token (178)) to the secondary TSP (116). From block (324), process (300) proceeds to block (326), which is performed by secondary TSP (116). In block (326), secondary TSP processor (194) processes the token request received from merchant (108).

From block (326), process (300) proceeds to block (327), which is performed by the selected network (124).

From block (327), process (300) proceeds to block (328), which is performed by issuer (120). In block (328), issuer processor (126) verifies the cardholder (104) account (e.g., the account data (142) associated with the secondary token (178)). From block (328), process (300) proceeds to logic branch (330), also performed by issuer (120). In branch (330), issuer processor (126) determines if the cardholder (104) account is verified. If issuer processor (126) determines in branch (330) that the cardholder (104) account is not verified, then process (300) proceeds to end state (310).

If issuer processor (126) determines in branch (330) that the cardholder (104) account is verified, process (300) proceeds to block (331), which is performed by the selected network (124). In block (331), the selected network (124) receives, and then transmits, the account verification to the secondary TSP (116). From block (331), process (300) proceeds to block (332), which is performed by secondary TSP (116). In block (332), secondary TSP processor (194) generates and/or provisions the secondary token (178). From block (332), process (300) proceeds to block (334), which is performed by merchant (108). In block (334), merchant processor (158) stores the secondary token (178) in merchant memory (166) (e.g., as side-by-side tokens (164) with primary token (176)). From block (334), process (300) proceeds to end state (310).

In block (510), merchant processor (158) sends an authorization request to the selected network (124) (e.g., primary (112) or secondary (116) TSP, selected based on the predetermined network routing preferences (170)). From block (510), process (500) proceeds to block (512), which is performed by the selected network (124). In block (512), processor(s) of the selected network (124) (e.g., primary (184) or secondary (194) TSP processor) create and/or send a detokenize request to the token vault (127 or 128, as shown in FIG. 1 ). From block (512), process (500) proceeds to block (514), which is implemented, at least in part, by token vault (127 or 128). In block (514), the primary (176) token or the secondary (178) token is detokenized (e.g., by primary (184) or secondary (194) TSP processor) in response to the detokenize request received from the selected network (124). In an embodiment, in block (514), a response to the detokenize request of block (512) includes an encrypted message. In an example, the network routing logic function(s) of, for instance, process (500), moves from the acquirer (192) to the merchant (108) wallet provider/e-commerce platform.

From block (516), process (500) proceeds to block (516), which is performed by the selected network (124). In block (516), selected network (124) processor (e.g., primary (184) or secondary (194) TSP processor) rebuilds (e.g., decrypts) the message and sends an authorization request to the issuer (120). From block (516), process (500) proceeds to block (518), which is performed by issuer (120). In block (518), issuer processor (126) authorizes the purchase or payment transaction between the cardholder (104) and the merchant (108), which involves the purchase card (106). From block (518), process (500) proceeds to logic branch (520), which is performed by issuer (120). In branch (520), issuer processor (126) determines if the transaction is authorized. If issuer processor (126) determines in branch (520) that the purchase or payment transaction is not authorized, then process (500) proceeds to an end state (522). In an example, the end state (522) transition in process (500) includes notifying the merchant (108) and/or the cardholder (106) that the purchase or payment transaction is not authorized.

If issuer processor (126) determines in branch (520) that the purchase or payment transaction is authorized, then process (500) proceeds to block (524), which is performed by the selected network (124). In an embodiment, in branch (520), an affirmative response to the authorization request of block (516) includes an encrypted message. In block (524), processor of the selected network (124) rebuilds (e.g., decrypts) the message and forwards the issuer (120) response to the merchant (108). From block (524), process (500) proceeds to block (526), which is performed by merchant (108). In block (526), merchant processor (158) confirms the purchase or payment request and provides a notification to that effect to the cardholder (104). From block (526), process (500) proceeds to end state (522). In an example, process (500) transitions from end state (522) to start state (502) iteratively for each of a plurality of purchase and/or payment transactions. In another example, a plurality of instances of process (500) run in parallel for processing a plurality of purchase and/or payment transactions simultaneously.
